Description

  The present invention is a portion package for producing an aroma drink, particularly coffee, wherein the portion package is provided with a pot-shaped lower portion, and the pot-shaped lower portion has a bottom portion and an annular side wall. The upper end of the side wall is provided with an edge extending outward in parallel with the bottom surface, and the pot-shaped lower portion is provided with a cover, and the cover (the lower edge is And attached to this edge, at least the lower part of which is made of a filterable material, as well as a device for the production of aroma drinks, in particular coffee. There is provided a hot water extraction chamber for accommodating a portion package filled with an aroma carrier, and the hot water extraction chamber has a stationary portion, an open position with respect to the stationary portion, and A hot water extraction chamber, which is movable to a chain position, for storing a portion of the hot water used for extracting the hot water after the insertion and closing of the portion package. It is of the type that is sealed on all sides, except for the outlet for

  Devices of the type described above, as well as portion packages for use in devices of this type, are known in various embodiments and are becoming increasingly popular. Because, on the one hand, the number of so-called single households specifically prescribed to use such devices is increasing, and independently of this, on the other hand, such devices are also used in multi-person homes. Because they are increasingly used to produce aroma drinks, especially a cup of coffee, quickly and without problems.

  Basically, such a device can be operated relatively simply.

  The hot water extraction chamber is opened outward from the closed position to insert the potion package, the potion package is inserted into the hot water extraction chamber, and when the hot water extraction chamber is closed, the switch is used to activate the hot water extraction process. Just turn it on.

  After hot water extraction of the aroma drink, the portion package with the extracted aroma carrier can be discarded.

  In order to obtain the best possible hot water extraction result, the potion package should be centered inside the hot water extraction chamber so that the hot water extraction water is guided through the aroma carrier inside the portion package with as little waste as possible. Is important, but this is not always guaranteed on the basis of the structure of the known device, as well as on the basis of the previously used portion packages.

  In many cases, the user of this type of device is urged to insert the portion package very carefully into the hot water extraction chamber. If care is not taken, the potion package will be accurately centered and not inserted into the hot water extraction chamber, and some of the hot water extraction water will flow through the aroma carrier passing through the hot water extraction chamber, so to speak. And therefore no longer participates in the extraction process. As a result, only poor drinks can be obtained.

  It is therefore an object of the present invention to improve such a portion package and device of this type so as to always ensure an optimum hot water extraction result with extremely simple operability. Furthermore, it is desirable that the portion package be superior on the one hand due to trouble-free operability, on the other hand, for practically suitable stability and for the possibility of relatively inexpensive manufacture.

  According to the solution of the invention, the portion package has at least two side walls facing each other in a wedge shape, and the receiving part of the device for producing a cup of aroma drink has a bottom surface. Has also a wedge-shaped insert for the progressively narrower front region of the wedge-shaped portion package, and a stop is provided in the stationary part in the end region facing said insert. By means of the stopper, the potion package is fixed in a predefined insertion position when the hot water extraction chamber is closed.

  The portion package has two side walls that extend wedge-shaped opposite one another and thus have a wedge-shaped profile. In this case, the portion package has a pot-shaped lower part, which has a bottom and an annular side wall, and an upper end of the side wall and an edge extending outwardly in parallel with the bottom surface. And a cover resting on this edge of the lower part and coupled to this edge.

  This type of portion package is based on a wedge shape that naturally conforms to the geometry of the hot water extraction chamber of the device of the present invention, so that it can be accurately fitted into a predetermined location in the corresponding hot water extraction chamber. Ideally suited.

  Due to the tightness of the side walls, the entire portion package has a relatively high stability, which is furthermore enhanced by the outwardly extending annular edges. This edge is likewise strengthened by the mounted cover area and the connection, forming a reinforced area of the portion package. This allows the potion package to be handled well and, by the above-described formation of the hot water extraction chamber, to ensure a final fit into the previously defined fitting when the hot water extraction chamber is closed, thereby providing a hot water extraction You can self-center to some extent inside the room.

  If the side wall of the portion package is sufficiently impermeable to water, the hot water extraction water may take a different path from the passage through the aroma carrier provided inside the portion package during the hot water extraction process. The danger that it can be avoided is also avoided.

  It is an inevitable and desirable consequence of the configuration of the present invention that a consistently good hot water extraction result is obtained.

  Advantageously, the tapered front area of the portion package is configured to be chamfered. That is, the wedge-shaped portion package is not pointed. The chamfer can be made large enough to provide a relatively large surface for the handle of the scraper or ejector. If the contact surface between one portion package and the other scraper or ejector is correspondingly large, a high surface pressure is avoided and a mechanical evaluation without the risk of breaking the portion package is possible. Guaranteed.

  Advantageously, the lower part and / or the cover are made of a filterable plastic-fleece or plastic-paper-mixture suitable for mass production.

  The device according to the invention has a receiving part in which a similarly wedge-shaped fitting for the progressively narrower front area of a portion-shaped package with a wedge-shaped bottom surface is provided with a projection of the portion-package. Is provided for overlapping with the edge area which has been set, in which case the stopper is directed to the end area of the stationary part which faces the fitting part, by means of which the closing of the hot water extraction chamber takes place. The portion package is fixed in a predefined insertion position.

  Due to the formation of the hot water extraction chamber of the device according to the invention having the features described above, the potion package can be heated even if the user does not take the necessary precautions when inserting the portion package into the receiving part. When the room is closed, it is ensured that it always assumes a precisely centered defined position. When the hot water extraction chamber is closed, the wedge-shaped portion package is slid into its defined position without the aid of the user, based on the formation of the hot water extraction chamber. This can be ensured on the one hand on the basis of the wedge shape of the hot water extraction chamber and on the other hand on the basis of the wedge shape of the portion package.

  Since the receiving part is provided with a fitting part and an undercut to overlap the protruding edge area of the portion package, when the hot water extraction chamber is opened after the extraction of the aroma drink, the portion package is Since it is held in the fitting part and therefore cannot remain attached to the stationary part of the hot water extraction chamber due to the adhesive force, an obstacle in disposing of the extracted portion package is prevented.

  Advantageously, a fixed part of the hot water extraction chamber is provided with a device for removing or removing the extracted portion package when the hot water extraction chamber is opened.

  As already mentioned, the automatic disposal of the extracted portion package is ensured by the ejector, since it is ensured that the extracted portion package does not adhere to the fixed or fixed part of the hot water extraction chamber. Can be performed without any problems.

  Next, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIGS. 1, 2 and 3 show schematic diagrams of a hot water extraction chamber provided in a device (not shown) for producing aroma drinks, especially coffee, one by one.

  The production of the aroma drink described above is performed using a potion package (package for one cup) 2. The portion package 2 is inserted into a hot water extraction chamber 1 provided for the portion package 2.

  In the context of the present invention, only the formation of the hot water extraction chamber 1 and the formation of the portion package 2 are concerned, so a detailed description of the device for producing an aroma drink is omitted.

  The hot water extraction chamber 1 mainly comprises a stationary part 3 and a housing part 4 which is movable with respect to the stationary part 3, in which case the housing part 4 accommodates the already described portion package 2 in a substantially form-fitting manner. It is provided in order to.

  In the embodiment shown, the movable part 4 of the hot water extraction chamber 1 is movable or slidable with respect to the stationary part 3 from the closed position shown in FIG. 1 to the open position shown in FIG.

  In the open position shown in FIG. 2, the portion package 2 can be easily inserted into the receiving part 4. After inserting the portion package 2 into the receiving part 4, the receiving part 4 is moved back to the closed position, the hot water extraction chamber 1 is provided with a water supply port for supplying hot water extraction water and an outlet for the produced aroma drink. With the exception of the outlet, it is sealed on all sides outward in any manner.

  The detailed description of the above-described supply port for hot water and the description of the discharge port for aroma drink are omitted.

  What is important in connection with the invention is that the receiving part 4 has a wedge-shaped insert 5 for the portion package 2 with a wedge-shaped bottom, which insert 5 is for mounting the hot water extraction chamber 1. The setting area 6 is provided with an undercut 7 for overlapping the protruding edge 8 of the portion package 2, and the fixed part 3 of the hot water extraction chamber 1 is provided with a stopper 9 at the end facing the fitting part 5. By means of this stopper 9, the portion package 2 is fixed to a predetermined end position inside the hot water extraction chamber 1 when the hot water extraction chamber 1 is closed.

  1, 2 and 3 show that the portion package 2 is placed in the placement area 6 of the receiving part 4 and the annular edge 8 has already been partially introduced into the undercut 7 of the fitting part 5. Is schematically shown. This is of course greatly simplified by the wedge shape of the fitting part 5 and the wedge shape of the portion package 2. If the hot water brewing chamber is closed by a corresponding movement of the receiving part 4, the portion package 2 abuts against a stop provided on the stationary part 3 of the hot water brewing chamber 1 and, if appropriate, a further fitting 5 Pressed into. In other words, there is no need for the user to take care to seat the portion package 2 absolutely accurately, which means that when the hot water extraction chamber 1 is closed, the stopper 9 causes the portion package 2 to be seated. In all cases, it is obtained automatically by moving it to a defined position inside the hot water extraction chamber 1. As a result, the portion package 2 is always centered within the hot water extraction chamber 1 without fail. In this case, “centered” with respect to the above statement means that the portion package 2 is always positioned inside the hot water extraction chamber 1 in an optimal position for the hot water extraction process.

  This takes into account that the hot water arriving at the hot water extraction chamber 1 is effectively forced to penetrate only the portion package 2 and not partially pass along the outside of the portion package 2. Important if you want to.

  Further, the undercut 7 of the housing portion 4 allows the portion package 2 to be always released from the stationary portion 3 when the hot water extraction chamber 1 is opened, without adhering to the stationary portion 3. This is because, as already described, the portion package 2 is held by the housing portion 4 or the fitting portion of the housing portion 4.

  FIGS. 4, 5 and 6 are views of the portion package 2 already described from various directions.

  The portion package 2 mainly comprises a pot-shaped lower part 10, which has a bottom part 11 and an annular side wall 12, which side wall 12 extends outwardly in parallel to the bottom surface. 13 is provided at the upper end. The lower part 10 is provided with a cover 14. The cover 14 is placed on the edge 13 after filling the aroma carrier (Aromatraeger) into the pot-shaped lower part 10, and is joined to the edge. The portion package 2 has two side walls 16 extending wedge-shaped from each other, and these side walls 16 give the portion package 2 a wedge-shaped profile.

  The lower part 10 of the portion package 2 is made of a filterable plastic-fleece or plastic-paper-mixture, preferably by a deep drawing method. In this case, the area of the side wall 12 is sufficiently impermeable to tightness. Such consolidation of the side walls 12 on the one hand contributes greatly to the stabilization of the entire portion package 2, and on the other hand ensures that hot water extraction water cannot inadvertently flow through the side walls 12.

  The cover 16 is also preferably made of a filterable plastic fleece or plastic-paper mixture. The connection between the cover 14 and the edge 13 of the lower part 10 is advantageously obtained by means of a seal.

  The overlapping material layers of the edge 13 and the cover 14 form an edge 8 (see FIGS. 1 and 2) which engages in the undercut 7 of the receiving part 4.

  1 and 2, the annular side wall 12 of the portion package 2 is configured to conically taper by an angle α starting from the cover 14.

  The corresponding abutment surfaces 5a of the receiving part 4 are correspondingly chamfered obliquely, so that the potion package 2 can be additionally positioned on the receiving part 4.

  The stopper 9 of the stationary portion 3 of the hot water extraction chamber 1 is provided with a corresponding chamfer for an angle β, so that the stopper 9 entirely contacts the side wall 12 opposite the portion package 2. Has become.

  Due to the tightened area of the portion package 2 at various strengths, in particular the considerable tightness of the side walls 12 and the tightness of the annular edge 8, the portion package 2 can be handled, packaged and A stability is obtained which significantly improves the transportability, which, as already mentioned above, contributes to the fact that the portion package 2 has a very reliable and stable position inside the hot water extraction chamber 1.

  Overall, the hot water extraction chamber 1 and the portion package 2 are optimally coordinated with each other, so that the user of the device according to the invention can obtain an optimal result of hot water extraction when using the portion package 2 according to the invention. You do not need to pay more attention to

  As suggested in FIG. 5, in the area of the chamfered narrow side of the portion package 2 there is provided a relatively large surface A for abutment of a scraper or the like, in which case: Due to the size of this surface, a relatively slight specific surface pressure is obtained when the portion package 2 is removed or discarded. The destruction of the portion package 2 at the time of disposal is thereby substantially reliably prevented.

  Further, as can be seen from FIG. 5, a region 15 can be provided in the bottom 11 of the portion package 2, and the water permeability of this region 15 is formed higher than other regions of the bottom 11. This can be achieved by providing different strength seals of material during the manufacture of the lower part 10. The same can be said for the cover 14 correspondingly. If the portion package 2 is provided in particular with a water-permeable region 15, this region 15 is preferably advantageously arranged so as to face the water supply opening inside the hot water extraction chamber 1. Thereby, the desired uniform penetration of the aroma carrier inside the portion package 2 can be remarkably promoted.

  7 and 8 show an apparatus for producing an aroma drink. The apparatus has a hot water extraction chamber 1 into which a portion package 2 can be inserted. The device has a receiving part 4 and a wedge-shaped fitting 5 for a portion package 2, which is movable relative to the receiving part 4, also having a wedge-shaped bottom. The fitting portion 5 is provided in a mounting range 6 which engages the portion package 2 so as to surround the portion package 2 in a C-shape, and the mounting range 6 overlaps the protruding edge 8 of the portion package 2. An undercut 7 for causing the undercut 7 is provided. When the hot water brewing chamber 1 is closed, the portion package 2 is pressed against a rear stopper 9 which moves the portion package 2 to a predefined position inside the hot water brewing chamber 1. The portion package 2 is thereby housed in the hot water extraction chamber 1 in a form-fitting centered manner.

  In order to remove the used portion package 2, the accommodation portion 4 is provided with a scraper 18 projecting downward. By moving outwardly of the fitting part 5, the web of the scraper 18 penetrates and engages with the slit 19 inside the side wall of the fitting part 5, and the portion package 2 is pushed out of the mounting range 6 and is lowered. Press the side wall of the portion package 2 facing the slit 19 until it falls or is sent to the disposal station. Other mechanisms for removing the portion package 2 from the mounting area 6 can also be used.

  In the embodiment shown, a pot-shaped lower part 10 and a cover 14 are provided. Of course, it is also possible to "turn over" the portion package and provide a plate-shaped bottom on the pot-shaped top.
